The information in this article applies to:

-------------------------------------------------------------------------------
 
SUMMARY
=======
 
Because of physical read limitations of some CD-ROM drives, you may be denied
access to some of the files and folders on the Microsoft Encarta Virtual Globe
1998 compact disc. This article lists those files and supplies a method to test
your CD-ROM drive.
 
MORE INFORMATION
================
 
The CD-ROM drive may have difficulty reading the final folder, listed below,
from the Encarta Virtual Globe CD-ROM:
 
+--------------------------------------+
| Folder            | Location On Disc | 
+--------------------------------------+
| System\Media\Home | 628-629 MB       | 
+--------------------------------------+
 
To test for specific drive-capacity limitations, try to access the following
files:
 
+--------------------------------------------------+
| Files                         | Location On Disc | 
+--------------------------------------------------+
| System\Media\Home\Bottom.spl  | 628-629 MB       | 
+--------------------------------------------------+
| System\Media\Avi\T174228a.avi | 606-608 MB       | 
+--------------------------------------------------+
| System\Media\Avi\18352.avi    | 568-571 MB       | 
+--------------------------------------------------+
| System\Fly\Uswest.fly         | 543-547 MB       | 
+--------------------------------------------------+
 
The Encarta Virtual Globe 1998 compact disc contains 629 MB of data. The final
file on the CD-ROM is System\Media\Home\Topb.spl.
 
Testing Your CD-ROM Drive
-------------------------
 
To test the integrity of files that you have copied from your CD-ROM drive to
your hard disk drive, compare the files using the MS-DOS File Compare program
(Fc.exe). You can use this to determine if the CD-ROM subsystem is functioning
properly at the device driver or hardware level(s).
 
The Fc.exe utility is a useful method for testing problems related to general
protection (GP) faults or other critical errors (such as read errors or out of
memory messages) that may occur when you use CD-ROM drives with Windows
programs.
 
Attempt to copy one of the following files to the hard disk drive:
 
+--------------------------------------------------+
| Files                         | Location On Disc | 
+--------------------------------------------------+
| System\Media\Home\Bottom.spl  | 628-629 MB       | 
+--------------------------------------------------+
| System\Media\Avi\T174228a.avi | 606-608 MB       | 
+--------------------------------------------------+
| System\Media\Avi\18352.avi    | 568-571 MB       | 
+--------------------------------------------------+
| System\Fly\Uswest.fly         | 543-547 MB       | 
+--------------------------------------------------+
 
For more information about how to perform this task in Windows, see your Windows
printed documentation or online Help.
 
If the following error message appears
 
   CDR101: Not Ready
 
the CD-ROM drive cannot read the disc at the specified location. If the file does
copy, test the file's integrity by using Fc.exe with the /B (binary) switch. For
example, to compare the Bottom.spl file on the CD-ROM to the version of the
Bottom.spl file you copied to your hard disk drive, type the following at the
MS-DOS command prompt, and then press ENTER:
 
   fc /b d:\System\Media\Home\Bottom.spl c:\Bottom.spl
 
where D is the letter of your CD-ROM drive, and C is the letter of your hard disk
drive.
 
If you receive errors, the CD-ROM drive is having problems reading the compact
disc at that location.
